Carbon dioxide is produced by the decomposition of CaCO3. The reaction product yield is 80%. Calculate how much CO2 will be obtained from CaCO3 weighing 100 kg.
Decomposition of calcium carbonate: CaCO3 = CO2 + CaO.
M = 40 + 12 + 16 * 3 = 40 + 12 + 48 = 100 is the molar mass of calcium carbonate.
n = 100000/100 = 1000 mol is the amount of calcium carbonate substance found by dividing mass by molar mass.
According to the reaction equation, there is one mole of carbon dioxide for one mole of calcium carbonate. This means that the amount of carbon dioxide substance is 1000 mol.
The molar volume is 22.4 liters.
22.4 * 1000 = 22400l – the volume of carbon dioxide at one hundred percent product output.
22400 * 80/100 = 17920l – the answer.
